Tennis coach Judy Murray has a new rival to keep an eye on - the Duchess of Cambridge.

Kate joined Edinburgh school pupils and teachers as they were taught the basics of tennis in a clinic hosted by Ms Murray.

Often seen in the royal box at Wimbledon and described as a "keen" tennis player, Kate showed off her skills as she balanced and spun a racquet at Craigmount High School.

The class was part of the Tennis on the Road project created by Ms Murray in 2014 with the aim of growing the game at a grassroots level.

The meeting between Kate and Judy came weeks after Ms Murray became a grandmother. Andy's wife Kim gave birth to their daughter Sophia Olivia on February 7.

Speaking at the end of the day, Ms Murray said Kate's participation in the class was "fantastic for tennis and women's sport".

"She said she'd love to come back and do some more," she added. "From a parent's perspective, I think she was interested in what she could pass on.

"She asked me: 'At what age can a child hold a racquet?' I told her with children of George's (her son's) age you can start with a balloon and just the hand. I don't know if he has played yet, but she was certainly asking. If you start simple and a child can do it, then a child enjoys it and everything grows from there."

Despite teaching sons Andy and Jamie, Ms Murray said she would not be pushing a racquet into the hands of her new granddaughter. "No, I'm going to teach her how to dance," she joked.
